I am using Intel i5-3337U processor. I want to get several perf events for a process via PID.
However when I am running perf stat command with several events for some seconds,in some execution its giving stats but sometimes its displayed all counters as "<not counted>"..
Could you please tell me the probable reason for that and how to get rid off this problem?
No I am not using Vtune to get perf stats data, rather I am using only commands.
I am using Ubuntu 12.04 LTS ,(kernel version: 3.5.0-23 generic).
perf stat -e instructions,cycles,cache-
This is the forum for VTune Amplifier XE product.
I don't know why you can't use perf, but I know that perf can be used within VTune Amplifier, then import perf result into VTune
Please see the example in this article.
